Configuring the BIOS hardware clock

The hardware clock is configured during initial BIOS configuration and can also be configured directly within the BIOS by using the BIOS setup utility. Use this procedure to modify the hardware clock settings during an installation without entering BIOS configuration directly.

The system clock of the runtime server is a software-based clock, separate from the hardware clock in BIOS. It is read by the Linux kernel as the runtime system initializes, providing the seed time for the software-based clock. Shortly after the system initializes, the NTP daemon running on the local server initiates its protocol with the configured clock sources to perform time synchronization.
